I noticed no one has replied to you (they are probably out hitting at this time or something.... it is the weekend... I know I would be if I didn't work weekends....) so I decided to try to help you out. I don't use gauze but this link might help you out:

I used to use gauze for many years. It's cheap and pretty tacky. It's a fairly rough feeling for the hands, but you get used to that. Probably not good if you have soft hands that are prone to blisters. It rounds off the bevels of the handle a bit, which is a minus. The main reason I stopped using it is because I thought it got a bit slippery under hot, sweaty conditions. It's Tournagrip for me now, as my hands sweat a lot.

I have mentioned this before in overgrip threads only to get deafening silence and the occasional cricket as a reply. Gauze rocks - no, it is no so tacky it makes changing grips hard. It it cheap - Kmart near me has Unique gauze for 1.99 or something a role, which is enough to grip a single racquet half a dozen times or so. I have at least 6-7 roles in my bag. I sweat big time, I could never use tournagrip - too expensive and wears out way to quick. Been using gauze since high school (um, yes the 80s) and love it.

I have not seen it used in a long time...You got me thinking back to those good old days - when everyone was using it. Cheap, and best of all quick and easy to apply. Might be fun to try it again!

does gauze end up to be sticky or not? I bought the Unique one but haven't tried yet. My problem is that my overgrip, still a pretty much tacky ones, feels slippery at times since I really really sweat a lot. Would gauze help?

Trying to remember how it felt as I used gauze-tex in college (30 yrs ago). Prior to commercial overgrips, gauze was the only game in town. Dirt cheap. Very tacky and easy to change. Rough on the hands, but then all we had was leather grips anyway, so how bad could it be? A little greasy if you sweat in the hand area.

Yes, the gauze would help - the nice thing about it is it is thin so it is not like you are building up your grip. You can easily put it over your current overgrip.

Do it ace, pick some up, we can start a gauze revolution. Speaking of the good old days, I was at a yard sale yesterday and picked up two packs of addidas socks (new unused) that I am positive are from the 80s. This lady had a bunch of stuff like that still in the original package in her attic. It is the old addidas logo - two three packs. They are so cool - can't wait to hit the court, gonna feel like Lendl running around in those things

I just finished to put it on, I hope I will be able to give it a try tomorrow. Feels rough but at the same time not slippery at all. Kinda rounds the bevels. I hope it works well with sweat, tomorrow or so will post a feedback.

If you think it is rounding out the bevels then you are probably using too much. Properly applied gauze improves your grip with out adding any cushioning, increase in size, or losing the bevels at all.
